I ran into this rate limit recently when generating a logo in SVG. It's 45 messages per 5 hours (with some caveats). It's documented here [0].

> Your limit gets used up faster with longer conversations, notably with large attachments. For example, if you upload a copy of The Great Gatsby, you may only be able to send 15 messages in that conversation within 5 hours, as each time you send a message, Claude “re-reads” the entire conversation, including any large attachments.

Seems to also be limited by tokens. It’s still quite obscure.

Fine for the free tier of course, but not great for the paid version.
